Residual Trapping – what happens after CO2 injection?

  A total of 10 talks discussing trapping mechanisms for CO 2 were presented at GHGT-13 on Tuesday. This included new research from Stanford University (Charlotte Garing et al.) which demonstrated, through micro-CT imaging experiments, the residual trapping effects that occur at pore-scale within the reservoir (and the impact of capillary pres...

Calculating CO2 storage resource – which way is the right way?

As part of the Risk Assessment session held at GHGT-13, Scott Frailey from the Illinois State Geological Survey spoke about the issues surrounding the variety of techniques currently used to calculate storage resource and their associated uncertainties. He announced that The Society of Petroleum Engineers CCS Technical Section is forming a multi‐so...

Quest one year on

The GHGT-13 plenary session on Wednesday 16th November opened with an upbeat assessment of the Quest CO 2 storage demonstration site in the Canadian province of Alberta. Tim Wiwchar, who is Shell Canada's Portfolio Manager Heavy Oil, presented a summary of the progress since this flagship project started operating in November 2015. Quest was built ...

Advances in wellbore integrity

 CO 2 storage relies on the injection of the gas either via pre-existing wellbores or, in the future, new wells. CO 2 is potentially corrosive and in certain conditions can induce rapid cooling. Both conditions are detrimental to wellbores so it's important to understand how these conditions occur and what mitigation options are available. The...

Opening Speech GHGT-13 Kelly Thambimuthu

  As I spoke to open GHGT-13 today COP22 is underway in Marrakech. It is worth reflecting on the historic agreement that was made at the preceding COP21 meeting held in Paris last year. Paris set us the added aspiration of a new global temperature target of below 20C, even though we are working towards a 2 0 C target. We know very well that ev...

Pressure Testing Experiment at the Swiss Mont Terri Rock Laboratory

  The Swiss are making an important commitment to long-term CO 2 storage through international collaboration and research. This is notably evident at the Mont Terri Rock Laboratory situated in the Jura Mountains about two hours drive north of Lausanne. This facility has been deliberately constructed within an impermeable shale called the Opali...

The use of natural analogues to study patterns of CO2 migration.

 The geomechanics session at GHGT-13 in Lausanne has covered a variety of topics including the value of studying natural analogues. Useful insights into CO 2 migration within formations can be gained especially where fractures provide natural conduits for geochemical alteration. Exposures of the Jurassic Entrada formation in Utah provide an ex...

“Keep calm and carry on” - COP-22 underway, with CCS events, and American developments.

COP-22 got underway in Marrakesh in unseasonable heavy rain. Several thousand delegates are gathering at the tented city that is the conference centre for the work to start developing the implementation details of the Paris Agreement, in terms of frameworks, processes and mechanisms. Negotiations commenced under SBSTA on the Technology Framework in...

CTCN Makes Significant Progress

The Climate Technology Centre and Network (CTCN) set up in 2003 is the implementing arm of the United Nations Framework Convention on Climate Change Technology Mechanism. The CTCN, promotes the accelerated development and transfer of climate technologies for energy-efficient, low-carbon and climate-resilient development. On November 4th 2016 the CT...

New IEAGHG Report: 2016-13 Fault Permeability

Fault zones are widely recognised as being important to the secure long term storage of CO 2 as they could provide a leakage pathway out of the target reservoir. Fault characterisation within reservoirs, especially where they extend into caprock, and other overlying formations, needs to be thoroughly understood as part of any risk assessment for CO...

New IEAGHG report: Evaluation of process control strategies for normal, flexible and upset operation conditions of CO2 post combustion capture processes

  It is important for power plants to be able to operate flexibly to respond to changes in consumer demand for electricity. Flexibility is also becoming increasingly important due to the greater use of other low carbon generation technologies, particularly variable renewable generators. The issue of operating flexibility of power plants with c...

Regional Assessments of the Economic Barriers to CO2 Enhanced Oil Recovery in the North Sea, Russia and GCC States

  The use of CO 2 for enhanced oil recovery (EOR) is a well established commercial practice in the United States where it has been used for over 40 years. There is widespread potential for CO 2 -EOR in other mature petroleum producing regions. If CO 2 -EOR could be implemented it would offer an economic stimulus to develop CO 2 storage. There ...

Visit to Tomakomai Project

  During the CSLF week of meetings in Tokyo, the Japanese hosts RITE and JCCS Company arranged for a day visit to the Tomakomai project on the northern island of Hokkaido. This project is capturing CO 2 from a gas stream from the hydrogen production unit at the Tomakomai refinery using a unique two-stage pressure swing absorption system, and i...

Paris Agreement Enters into Force.

The Paris Agreement has now entered into force. To date 74 countries have joined the agreement, 55 were needed. These countries represent 58.83% of global greenhouse emissions, breaking the required 55% threshold. That was the easy bit, now the hard work starts, there a big hill to climb to get to below 2 degree C temperature rise.

Climate Scientists say 1.5C is inevitable.

  In a recently published paper called "The Truth about Climate Change", a group of climate scientists tell us that, "By 2015, the global temperature had risen by 1°C above pre-industrial levels, that it is certain to rise another half a degree by 2030 and will continue to rise to 2°C by 2050 unless drastic action is taken to reduce emissions"...

Ratification of Paris Agreement moves closer.

  According to the UNFCCC as of today (23rd September 2016) 62 countries representing 49.3% of global CO 2 emissions have now ratified the Paris Agreement. To enter into force the agreement needs 50 countries representing 55% of global emissions to sign. So milestone one has been passed and milestone 2 is close to being achieved. At a single e...

Keeping up Momentum on HFC reduction.

  The Montreal Protocol is expected in October 2016 to agree an amendment to phase down HFC emissions. Ahead of that decision the US Government has this week hosted a meeting with over 100 delegates who called for securing an ambitious amendment with an "early freeze date". The freeze date is the year when countries stop increasing the product...

China and USA Ratify Paris Agreement

  At the G20 meeting in Japan China and the USA have both announced their intention to ratify the Paris Agreement. This means that he two biggest emitters of greenhouse gases have committed themselves to the principle of moving to a temperature target of below 2 degrees centigrade. Both countries have now formally lodged their instruments of r...

Global Warming started in 1830’s

  New research led by Australian scientists, and recently published in the journal Nature suggests human impacts had begun to change the climate as back as the 1830's, earlier than previously expected. Their conclusions were based on natural records of climate variation in the world's oceans and continents, including those found in corals, ice...
